Abstract

a. Chambre de coupure pour les disjoncteurs électriques à grande puissance de coupure. b. La chambre de coupure est conçue pour obtenir l'effet COANDA à l'instant de l'ouverture des contacts, ce qui permet d'augmenter la puissance de coupure des disjoncteurs électriques haute tension, performance réalisée indépendamment de la forme des contacts, indépendamment de la nature de l'agent extincteur et indépendamment de la forme géométrique intérieure de la chambre de coupure. c. Centrales et postes électriques.
